Description

Technical Field

[0001] The utility model relates to the technical field of flue gas purification, and more specifically, to a flue gas purification device for aluminum electrolysis. Background Art

[0002] Electrolytic aluminum is an important method for producing aluminum. The principle is to use electrolytes, such as aluminum fluoride and aluminum chloride, to reduce the aluminum ions rich in them into aluminum metal under the action of electrolysis, and then become electrolytic aluminum products after purification and ingot casting.

[0003] During the electrolysis of aluminum, the bubbles on the cathode will contain some free forms of fluorides. These bubbles will burst on the surface of the liquid metal, causing volatiles such as silane, chlorosilane and fluorosilane to decompose, thereby generating flue gas. These flue gases are rich in pollutants such as sulfur dioxide and dust. These substances will irritate and damage the respiratory and immune systems after inhalation. In addition, the emission of flue gas into the atmosphere without effective treatment will aggravate the greenhouse effect and have an adverse impact on the global climate. Therefore, an aluminum electrolysis flue gas purification device is needed.

[0004] In order to make the gas meet the emission standards, absorption liquid is usually sprayed during purification to react harmful components in the flue gas with the absorption liquid to reduce its concentration. However, in order to ensure comprehensive spraying, multiple groups of sprinklers are usually set up. Although this method can spray more comprehensively, installing multiple groups of sprinklers will increase the workload and increase the economic burden. After the spraying is completed, a filtering device is usually set up to filter the dust in the flue gas. However, the filter plate is prone to blockage after working for a long time, delaying the emission of flue gas, so it needs to be improved and optimized. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] like Figures 1 to 6 As shown, the utility model provides an aluminum electrolysis fume purification device, comprising a purification chamber 1, an air inlet 2 is fixedly opened on the left side of the purification chamber 1, an air outlet pipe 3 is fixedly installed inside the purification chamber 1, the air outlet pipe 3 and the air inlet 2 are connected to each other, a spray pipe 4 is rotatably installed inside the purification chamber 1, and a dustproof shell 5 is fixedly installed on the right outer wall of the purification chamber 1;

[0033] The vibration mechanism is rotatably mounted inside the purification chamber 1, and one end of the vibration mechanism is transmission-connected to the driving mechanism;

[0034] Among them, the swing mechanism includes a worm gear 8 rotatably installed inside the dustproof shell 5, the worm gear 8 is transmission-connected to the driving mechanism, one end of the worm gear 8 is fixedly connected to the rotating block 9, one side of the rotating block 9 is fixedly installed with an output rod 10, the output rod 10 is movably installed inside the transmission rod 11, the transmission rod 11 is movably sleeved inside the limit block 12, the limit block 12 is fixedly installed inside the dustproof shell 5, and there are two groups of limit blocks 12, the two groups of limit blocks 12 are located on the front and rear sides of the dustproof shell 5, and are movably sleeved with the front and rear ends of the transmission rod 11.

[0035] When it is necessary to purify the aluminum electrolysis flue gas, the staff connects the absorption liquid and the water pipe 14 to each other, so that the absorption liquid passes through the water pipe 14 and is sprayed downward from the spray pipe 4, and then the staff starts the motor 6. The operation of the motor 6 drives the worm 7 to rotate, and the rotation of the worm 7 drives the worm wheel 18 and the worm wheel 2 15 to rotate. The rotation of the worm wheel 8 drives the rotating block 9 to rotate, and the rotation of the rotating block 9 drives the output rod 10 to move. Since the transmission rod 11 is restricted by the limit block 12, the output rod 10 drives the transmission rod 11 to start moving left and right.

[0036] The worm 7 is rotated by the operation of the motor 16, and the rotation of the worm 7 drives the worm wheel 18 to rotate, which further causes the gear ring 13 to drive the spray pipe 4 to start to swing slightly.

[0040] The staff starts the motor 2 22 , and the operation of the motor 2 22 drives the gear 1 24 to rotate, which further drives the gear 2 25 to rotate, so that the stirring fan 26 starts to stir the absorption liquid.

[0041] The operation of the motor 22 drives the gear 1 24 to rotate, and the gear 1 24 further drives the gear 2 25 to rotate, so that the stirring fan 26 starts to stir the absorption liquid. Compared with the traditional device, the device can completely and fully contact the absorption liquid when the flue gas passes through the absorption liquid through the setting of the spoiler mechanism, thereby improving the purification degree of the flue gas and improving the purification efficiency.

[0043] The rotation of the worm gear 8 drives the rotating block 9 to rotate, and the rotation of the rotating block 9 drives the output rod 10 to move. Since the transmission rod 11 is restricted by the limit block 12, the output rod 10 drives the transmission rod 11 to start moving left and right. The left and right displacement of the transmission rod 11 drives the gear ring 13 meshing with it to rotate slightly left and right.

[0050] The working principle and use process of this utility model:

[0051] When it is necessary to purify the aluminum electrolysis flue gas, the staff connects the absorption liquid and the water pipe 14 to each other, so that the absorption liquid passes through the water pipe 14 and is sprayed downward from the spray pipe 4, and then the staff starts the motor 6. The operation of the motor 6 drives the worm 7 to rotate, and the rotation of the worm 7 drives the worm wheel 18 and the worm wheel 2 15 to rotate. The rotation of the worm wheel 8 drives the rotating block 9 to rotate, and the rotation of the rotating block 9 drives the output rod 10 to move. Since the transmission rod 11 is restricted by the limit block 12, the output rod 10 drives the transmission rod 11 to start moving left and right. The left and right displacement of the transmission rod 11 drives the gear ring 13 meshing with it to rotate slightly left and right. The rotation of the gear ring 13 drives the spray pipe 4 to rotate left and right, so that the spraying range is increased. It is worth mentioning that since the water pipe 14 adopts a rubber water pipe, the water pipe 14 can be slightly twisted. At the same time, the worm wheel 2 15 also starts to rotate. The rotation of the worm wheel 2 15 The driving rod 16 is driven to rotate, and the rotation of the driving rod 16 will squeeze the abutment plate 21, so that the abutment plate 21 drives the knocking head 19 to move, and the knocking head 19 will knock on the right side of the filter plate 17 along the limiting groove 18, so that the filter plate 17 starts to vibrate to prevent the filter plate 17 from being blocked.
